摘要
目的：探讨原发性肝癌的螺旋CT双期增强特征及其诊断价值。材料和方法：回顾性分析56例经，临床及手术病理证实的原发性肝癌双期增强表现。结果：56例共发现82个病灶。平扫呈低密度或等密度；肝动脉期91％强化，9％无明显强化；门脉期76％呈低密度或稍低密度，病灶密度呈“速升速降”的变化特点。结论：螺旋CT双期扫描可充分反映原发性肝癌的特征，对肝癌的检出和定性准确率的提高有重要价值。
Objective ： To investigate the hepatocellular carcinoma enhanced dual - phase spiral CT features and diagnostic value. Materials and Methods ： A retrospective analysis of 56 cases confirmed by clinical and surgical pathology of primary liver cancer dual - phase enhanced performance. Results： 56 eases were found in 82 lesions. Scan showed low - density or iso - density; 91% enhanced hepatic arterial phase, 9% had no significant enhancement ; portal venous phase was 76% low - density or a little low - density, lesion density was, ＂speed up downhill＂ change characteristics. Conclusion： The dual -phase helical CT scans can be fully reflected in the characteristics of primary liver caneer, liver cancer detection and qualitative improvement of accuracy of great value.
